Solução de problemas
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.

O que os usuários dizem
“IDEC HW series is my go-to for small jobs. Cheaper than Omron A22 and the quality is comparable. The only time I reach for Omron is when the customer specifically requests it or the panel has other Omron components.”
